(Boston University Computer Science Department, 2006-12-16)In this project we design and implement a centralized hashing table in the snBench sensor network environment. We discuss the feasibility of this approach and compare and contrast with the distributed hashing architecture, ...
-
(Boston University Computer Science Department, 2006-07-14)It is useful in systems that must support multiple applications with various temporal requirements to allow application-specific policies to manage resources accordingly. However, there is a tension between this goal and ...

(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-05)We can recognize objects through receiving continuously huge temporal information including redundancy and noise, and can memorize them. This paper proposes a neural network model which extracts pre-recognized patterns ...
-
(Boston University Computer Science Department, 2008-09-11)Localization is essential feature for many mobile wireless applications. Data collected from applications such as environmental monitoring, package tracking or position tracking has no meaning without knowing the location ...
-
(Boston University Computer Science Department, 2004-04-23)A system is described that tracks moving objects in a video dataset so as to extract a representation of the objects' 3D trajectories. The system then finds hierarchical clusters of similar trajectories in the video dataset. ...

(2011-07-14)A simple procedure for the isolation of caffeine from energy drinks by solid phase extraction on a C18 cartridge. Quantitative analysis of the amount of caffeine by LC/MS is determined by referencing a standard curve.
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2005-09)In experimental studies of visual performance, the need often emerges to modify the stimulus according to the eye movements perfonncd by the subject. The methodology of Eye Movement-Contingent Display (EMCD) enables accurate ...

(Boston University Computer Science Department, 2005-06-10)Nearest neighbor search is commonly employed in face recognition but it does not scale well to large dataset sizes. A strategy to combine rejection classifiers into a cascade for face identification is proposed in this ...
-
(Boston University Computer Science Department, 2005-07-07)Facial features play an important role in expressing grammatical information in signed languages, including American Sign Language(ASL). Gestures such as raising or furrowing the eyebrows are key indicators of constructions ...
-
(Boston University Computer Science Department, 2000-01-10)Recent work has shown equivalences between various type systems and flow logics. Ideally, the translations upon which such equivalences are based should be faithful in the sense that information is not lost in round-trip ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-07)The ARTMAP-FD neural network performs both identification (placing test patterns in classes encountered during training) and familiarity discrimination (judging whether a test pattern belongs to any of the classes encountered ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-02)We obtain a bound on the expected error rate of the fuzzy ARTMAP neural network employed as a classifier. This bound is based on leave-one-out estimation of the classification error, and is analogous to a bound on the ...
-
(Boston University Computer Science Department, 2002)We present new, simple, efficient data structures for approximate reconciliation of set differences, a useful standalone primitive for peer-to-peer networks and a natural subroutine in methods for exact reconciliation. In ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-05)A fast and efficient segmentation algorithm based on the Boundary Contour System/Feature Contour System (BCS/FCS) of Grossberg and Mingolla [3] is presented. This implementation is based on the FFT algorithm and the ...
-
(CS Department, Boston University, 2010-03-31)This paper presents an algorithm for recovering the globally optimal 2D human figure detection using a loopy graph model. This is computationally challenging because the time complexity scales exponentially in the size of ...
-
(Boston University Computer Science Department, 2005-07-07)Accurate head tilt detection has a large potential to aid people with disabilities in the use of human-computer interfaces and provide universal access to communication software. We show how it can be utilized to tab through ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-08-01)The recognition of 3-D objects from sequences of their 2-D views is modeled by a family of self-organizing neural architectures, called VIEWNET, that use View Information Encoded With NETworks. VIEWNET incorporates a ...
-
(Boston University Computer Science Department, 1998-12-04)An improved technique for 3D head tracking under varying illumination conditions is proposed. The head is modeled as a texture mapped cylinder. Tracking is formulated as an image registration problem in the cylinder's ...
